In order to achieve the above purpose, the utility model provides a hinged hook type elastic sling connecting device, which comprises an upper clamping plate, a lower clamping plate and a wiring terminal, wherein the upper clamping plate and the lower clamping plate are connected through a bolt assembly, one side of the upper clamping plate, which is opposite to the lower clamping plate, is provided with a limiting groove corresponding to a carrier cable, two ends of the upper clamping plate and the lower clamping plate are respectively provided with a connecting through hole which is positioned at the axes of two sides of the carrier cable and extends up and down correspondingly, the limiting groove is an arc-shaped groove, the diameter of the limiting groove is larger than the diameter of the carrier cable, the depth of the limiting groove is smaller than the radius of the carrier cable, and an oval carrier cable accommodating channel is formed through the limiting grooves which are opposite up and down;
The bottom side of lower plate is equipped with the couple that is used for connecting the C type of elastic sling, be equipped with the link on the binding post, the link is hung and is established on the couple, the opening part of couple is equipped with the hasp, be connected with the wire jumper between end connection spare and the punch holder.
In the scheme, the method comprises the following steps: the top of punch holder and the bottom of lower plate correspond the connection through-hole at both ends and all are protruding to be equipped with the boss of strengthening, improve the intensity of punch holder and lower plate, be difficult for buckling or warp.
In the scheme, the method comprises the following steps: the upper clamping plate and the lower clamping plate are made of alloy, so that the hardness is high, the clamping force is strong, and the clamping requirement is met.
In the scheme, the method comprises the following steps: the anti-slip lines are arranged in the limiting grooves, so that the carrier ropes can be prevented from sliding.
In the scheme, the method comprises the following steps: the jumper wire is used for fixing one end of the upper clamping plate through a bolt assembly between the upper clamping plate and the lower clamping plate.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows: because elastic sling is different from the carrier cable and needs certain clamping force to fix the position, only need link together, adopt the mounting means of couple, compare prior art can improve installation effectiveness, only need hang can, reduce the operation degree of difficulty of high altitude construction, adopt the hasp simultaneously can prevent that the link from breaking away from, guarantee installation stability. The oval carrier cable accommodation channel that sets up can ensure the clamping force to the carrier cable, improves connection stability, and the diameter of spacing recess is greater than the diameter of carrier cable can ensure that the carrier cable can be located the carrier cable accommodation channel completely, avoids leaving the gap between carrier cable and the spacing recess bottom.
